The Notch Wear Safe Stainless Steel Ring is designed specifically for arboriculture, friction saver/cambium saver assembly, and the setup of high-altitude anchor points. The body is crafted from high-quality hot-forged steel with a breaking strength of up to 30kN, providing exceptional structural reliability.
Compared to traditional aluminum alloy rings, stainless steel offers superior surface wear resistance and corrosion resistance. It is less prone to developing grooves or sharp edges under prolonged rope friction, significantly enhancing safety for high-altitude work while facilitating daily visual inspection and maintenance. Available in Small (28x52mm) and Large (48x72mm) sizes, it is the ideal core component for friction saver systems.
Key Features
High-Strength Hot-Forged Steel: Boasts a robust 30kN breaking strength for stable load-bearing, providing a high level of safety redundancy for high-altitude operations.
Ultimate Wear Resistance: The steel hardness is significantly higher than that of aluminum alloy, resisting long-term repetitive friction from main ropes without easy wear or indentation, effectively extending service life.
Smooth Edges for Rope Protection: The ring's contact surfaces are precision-rounded for smooth rope guidance, effectively reducing wear and minimizing damage to both tree bark and ropes.
Classic Large/Small Ring Compatibility: Available in 28x52mm and 48x72mm sizes, allowing for precise pairing to create traditional friction savers that are easy to throw and retrieve from the ground.
Easy Inspection and Maintenance: The surface is hard and uniform, facilitating quick checks for wear and cracks before use, with excellent weather and rust resistance.
